Original Abstract Submitted
the present invention provides an apparatus for inspecting a welding state in a welded portion for an electronic or mechanical coupling in a lithium secondary battery, the apparatus including: a measuring unit configured to obtain data for deriving a resistance value of the welded portion by allowing a resistance measuring probe to contact the welded portion; and a controller configured to communicate with the measuring unit, determine the resistance value of the welded portion by receiving the data obtained from the measuring unit, and determine whether a weak welding was performed by comparing the determined resistance value with a threshold resistance value, in which the measuring unit is configured to allow the resistance measuring probe to contact one end and the other end of the welded portion.
